DISCOVERY
 * Molybdenum was discovered in 1778, by Carl Wilhelm Scheele. Molybdenum was once confused as graphite and lead ore. Carl Scheele discovered it was neither graphite nor lead ore. Molybdenum was first isolated in 1781 by Peter Jacob Hjelm. **


 * Molybdenum is used in alloys, electrodes, and catalysts. Molybdenum is also found in such minerals as wulfenite and powellite. (MO) is recovered as a byproduct of copper and tungsten mining. The world’s largest producers of Molybdenum materials are the United States, China, Chile, Peru, and Canada. This metal is used in nuclear energy, missile and aircraft parts. It has also been found in electronic and electrical appliances.
